摘要: Electrical Impedance Tomography (EIT) can resolve dynamic physiological information deep within human subjects [1], but its sensitivity is challenged in the case of imaging head [2]. Here, we report a new system called fEITER that has been designed and built to enable functional brain using EIT via scalp-mounted electrodes, integrated with stimulation evoked responses. Using Field-Programmable Gate Array (FPGA) technology, it provides excellent flexibility terms current-pattern excitation signal processing. The instrument operates at 100 frames/second (fps) noise 1 μV on rms voltage measurements. Clinical trials have authorized by UK MHRA example data from are presented.
